I am using MHD (used to use BM3). The data comes from there. If I go through extra effort, I also incorporate data from the Apex Pro app (g force primarily). It has an excellent refresh rate - I am actually recording more than what's shown and it's quick. I believe there are different rates for different fields (like transmission, water, and oil temp which wouldn't need more than 1 hz), but I couldn't quickly confirm that so don't quote me.
One last thing...this has also helped me to diagnose that during this event my wastegate got stuck in a partially open/closed position...I was able to look at the boost, relative to RPM and Accel and WGDC to see that it wasn't building boost like it should have been. It's very helpful in coordination with the video!

what do you use to record the engine RPM and accel? seems to have really high refresh rate considering you also record other temps.
